Deepavali firecrackers pollution: 99 of the 265 cities for which Air Quality Index (AQI) data were available on the Central Pollution Control Board website reported “poor” air quality on November 1, 2024
Ninety nine of the 265 cities for which Air Quality Index (AQI) data were available on the Central Pollution Control Board website reported “poor” air quality on Friday, November 1, 2024 (data for 24 hours prior to 4 p.m. on this day).
An AQI value of 200 or above corresponded to “poor” quality.
Thirteen cities, including Delhi, Gurugram and Ghaziabad in the National Capital Territory Region, recorded “very poor” air quality — AQI of 300 or above.
Ambala in Haryana and Amritsar in Punjab recorded the highest values of 367 and 350, respectively, while Delhi’s average AQI was 339.
These 24 hours corresponded to the period when Deepavali revellers took to burning crackers, defying a ban on it in places such as Delhi. Revellers burnt crackers on Thursday (October 31, 2024), before 4 p.m. as well.
On Thursday (October 31, 2024), the number of cities that had “very poor” and “poor” air quality was relatively fewer — six, including Delhi (second highest AQI of 328), and 43, respectively. On Wednesday (October 30, 2024), a day prior to Deepavali celebrations, only Delhi registered “very poor” air quality, with an AQI of 307. The number of cities with “poor” AQI was even fewer — 24, almost all of them in North India.
Large cities such as Mumbai, Chennai, Bengaluru, Hyderabad, and Kolkata registered a “moderate” AQI on Friday, but even among them, the AQI values had jumped from those registered on October 30.
